Improvement in spindles for loom-shuttles

ALBERT MORTON,"OF SALMON FALLS, NEW HAMPSHIRE.

IMPROVEMENT IN SPINDLES FOR LOOM-SHUTTLES.

To all whom it may concern: I

Be it known that I, ALBERT MoRToN, of Salmon Falls village, town of Rollinsford, in the county of Stratford and State of New Hampshire, have invented a new and useful Improveshuttles; and it consists in the applica-tion to the spindle of the shuttle of a lever or cam, in such manner that when the cop or tube is applied to the spindle it causes the cam or lever to engage it in the interior near the base in a manner to insure the holding of the cop or tube till all the yarn is properly delivered, and prevent the escape of any except in the regular course.

Figure l is a side elevation of a shuttle-spindle provided with my improvement, and Fig. 2 is a longitudinal section of the same.

Similar letters of reference indicate corresponding parts.

A long slot, A, is made through the spindle, between the heel and point, nearly its whole length, and a long at lever, B, of steel or other suitable metal, is fitted in said slot and pivoted at C, so that near both ends it will rise above the surface of the spindleas indicated at D and E. At D the part so rising above the spindle is preferably notched, as shown, but not necessarily, for it will answer well without. The spindle and lever are so arranged as to size, relatively tothe cop or tube to be put on, that the end E will be forced down sufciently to raise end D up to press hard against the Wall of the hole through the bobbin or cop thereabout, and hold them from slipping oif when the yarn becomes slack, when nearly all drawn olf, so that the friotion is not sufficient to hold it. The said lever is also so arranged with the spindle that the weight of the arm terminating at E, which is much longer than the other arm, throws the latter up, when the yarn is unwound from the part of the spindle along the said long arm with suficient power to retain the yarn. Two or more of these levers or cams may be used, if preferred.

This improved cop-retainer may be applied to other spindles as well; for instance, the spindles of spoolers; and I propose to make such applications.

Having thus described my invention, I claim 'as new and desire to secure by Letters Patent- The iat lever B pivoted at G in a long slot, A, of the spindle, and having one arm, E, heavier than the other, D, when applied as and for the purpose specified.
